The effect of surgical treatment on pain and scoliotic curve in spine with osteoid osteoma and osteoblastoma

Abstract

Objective: The aim of this study was assess the results of local resection without instrumentation in patients with scoliosis secondary to spinal osteoid osteoma and osteoblastoma.
Methods: The review of our database revealed 176 cases of osteoid osteomas and 18 of osteoblastomas. Painful scoliosis was seen in 5 out of 6 cases. The lesion was found on the posterior part of the apical vertebra in the concave side of the scoliotic curve. Surgical treatment consisted of simple en bloc excision. Mean period between diagnosis and operation was 2.6 years, mean age at the time of surgery was 12.5 years, and mean preoperative major Cobb angle was 37.2°.
Results: Four patients with a mean follow-up of 4.3 years were included in the study. At final followup, Cobb angle was 7.6°, and the average percentage of correction was 79.6%. Coronal decompensation was corrected by 87.7%. Pelvic tilt and shoulder imbalance were corrected by 15% and 74.5%, respectively. The preoperative mean Visual Analog Scale score was 9 before the treatment and 0 at the final follow-up.
Conclusion: Our results suggested that simple en bloc resection may be a safe and effective treatment option in patients with scoliosis secondary to spinal osteoid osteoma and osteoblastoma, if patient less than 16 years, with major Cobb angle less than 40°, and duration of complaint less than 22 months.
